I have a DSO4254B
all this implied for me
device does not boot
and does not turn on the screen
only the LEDs on the right

Help

now if i don't know what to do

I disassembled the device and saw that all the information of the EEPROM and the operating system is stored in a Nand memory IC TSOP-48, 3V "IS34ML01G084", someone has a programmer to give me a copy of the Nand, they would be very grateful.
